Quickly rewatching Terminator 1 before I head out to see Genisys. Seems every time I see one of the movies or read one of the comics, some new rabbit hole opens up for me to dive into.
So, the Terminators job is to kill off Sarah Connor without threatening the integrity of the timeline. Okay, so ya can't just teleport a flesh coated nuke back. But its way of achieving this is to brutally murder all Sarah Connors in the order they're listed in the phone book, a method that the local police pick up on after only two murders (the minimum amount it takes to make that connection, by the way). Now, lets say that the actual Sarah wasn't name number three on the list, or that the police picked her up a minute before the Terminator had got to Technoir. What would have happened?
Well, every other Sarah in the city would have been taken to protective custody, meaning that the Terminators mission was now scattered and hidden. The only way to progress was to wage war on the police, prompting the Sarahs to constantly be moved and the fighting to escalate.
Now, what would have threatened the creation of a global security A.I. more, an umprompted nuclear attack on the Unite States with no organization taking credit, or a fucking cyborg waging open war on it?
